FLUSH-TANK MECHANISIVL Application filed July 19, 1916.

1 0 oil whom it '7)? m concern Be it known that I, Enwixnn P. Lacey, acitizen of the United States, residing at Zolit'o, in the county of DeSoto and State ot l lorida, have invented certain new and use t'ulImprovements in Flusl'i-Tunk Meclnv nisms; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to valves for flush tanks and has for an objectto provide a new and improved valve wherein the end of a protruding pipeis covered by an improved term of hell with a vent therein for supplyingair to the bell under certain conditions.

A. further object of the invention is to pro vide a bell form of valvewherein a tube leads from the top of the bell downwardly, so that whenthe. bell is in normal or closing position the tube is wholly submerged,and when raised to flushing position the tube serves to admit air to thebell.

With these and other objects in view the invention comprises certainnovel features of construction, combination and arrange ment of parts aswill be hereinafter more fully described and claimed.

In the drawings Figure 1 is a vertical longitudinal sectional viewthrough a tank showing the improved valve in position.

Fig. 2 is a transverse sectional view taken on line 2-2 of Fig. 1showing the balanced relation between the water in the tank and in thetrap.

Like characters of reference designate corresponding parts throughoutthe several news.

The improved valve which forms the sub jcct-matter of this applicationis adapted to be employed in any usual and ordinary type of flush tankas shown at 10, having a feed pipe 11 and ball valve 12, controlled bythe float -3, all in the usual and ordinary manner.

Extending upwardly within the tank is an outlet pipe 14: communicatingwith a trap 15, the latter discharging at 16 to the utensil to beflushed.

Disposed over the upper end of the pipe 1 is a bell 17 hinged in anyapproved manner as by employing the bracket 18, and controlled by meansof a link 19 connected to Specification of Letters Patent.

SeriaI No. 110,124.

a lever 20 carried upon the rock-shaft 21, and externally controlled inany approved manner as by the handle 22.

The side of the bell 17 opposite the hinge 18 is provided with a sleeve23 into which is inserted a nipple 94. open at both ends. The positionand relation oi. the sleeve 52?; and nipple 2% are such that the nippleinclines downwardly to a point approximating the bottom of the bell 17.Into the upper side of the nipple 24: is secured a short piece of smalltubing bent to substantially right angles as shown more partici'ilarlyat Fig. 1. so that the outer or upper end of such small tubing 25extends a considerable distance above the opening in the outer end 01the nipple 24.

In operation, with the parts located as.

shown at full lines in Fig. 1, the water will be introduced into thetank, rising within the bell. 17 until the air in the bell 1T vtorcesthe water in the trap 15 to such a position as to exactly balance thewater column above the top of the water within the bell and to the topof the water in the tank. In other words, the water column indicated byC at Fig. 1 will exactly equal the water column indicated by C at Fig.2.

The several parts will be so adjustedthat the column C at Fig. 1 willstart from ad-v j acent the top of the pipe 1 1 and extend to the top ofthe water in the tank when the flow of water through the feed pipe 11has been stopped by raising the float 13. At this position the twocolumns C and C are exactly balanced.

When, however, the bell 17 is raised by manipulating the handle 22,water will flow down the pipe 14: and. the column will then be theheight from the top of the water in the tank to the overflow of thetrap, and will force the trapped water into the flushing receptacle.

hen the hell 1'? is raised to dotted line position, the water will firstflow througl'i. the nipple 24% to supply the space occupied by the airwithin the bell, but as the bell is only momentarily raised and isdropped back to position action is continued by the siphoning action ofthe column of water drawing the water in the tank upwardly through thebell and down through the pipe 142 until the Water has extended belowthe level of the nipple 24, when air admitted to the bell 17 will enterthe pipe 14- bet'ore the water has dropped entirely below the lower edgeof the bell, and the water contained in the trap 15 will remain therein.As the water fills up from the feed pipe 11 the end of the nipple 2a isfirst covered, but as the inner end of the vent 25 is higher than theouter end of the nipple 2% air is still admitted through that pipe untilthe water reaches the top of the tube 25, when further ingress into thebell 17 is interrupted.

I claim 1. A flush tank mechanism comprising in combination with a tank,a pipe extending upwardly in the tank and having an open upper end, abell covering -the open upper end of the pipe and hinged to swing, anipple communicating with the upper end of the bell and extendingdownward and open at both ends, a vent tube leading from the nipple to apoint within the tank below the normal water line and above the lowerend of the nipple and means to raise the bell upon its hinge.

2. A l'lush tank mechanism comprising in combination with a flush tank,a pipe extending upwardly within the tank and having an open upper end,a bell over said pipe, a nipple communicating with the upper end of thebell and extending diagonally downward to a point adjacent the bottom ofthe bell and having an open outer end, and a bent tube occupying a smallportion of the nipple and having its opposite ends above the uppermostportion of the open outer end of the nipple.

3. A flush tank mechanism comprising in combination with a flush tank, apipe extending upwardly into the tank and having an open upper end, abell covering the pipe, a nipple communicating with the upper end of thebell and extending diagonally down-- ward to a point adjacent the bottomof the bell, a bent tube inserted in the lower end of the nipple andhaving its opposite ends above the uppermost open portion of the nipple,and means to raise the bell until the nipple and tube extend above thebell.

In testimony whereof I ailix my signature.
